What integration.app does
Membrane Inc. (formerly Integration.app) is a Delaware-incorporated, remote-first software company founded in 2021 that provides agentic integration infrastructure for SaaS companies and AI agent builders. The platform allows developers to connect AI agents and software products to any of 100,000+ third-party applications through a single interface, eliminating the traditional trade-off between time-to-implementation and customizability in customer-facing integrations.
The core platform consists of four pillars: (1) the Membrane integration engine featuring Universal Data Models that abstract third-party API schemas; (2) Membrane Agent, an AI agent that autonomously builds, tests, and maintains integrations from natural-language descriptions; (3) Membrane Universe, a knowledge base of pre-built connectors and production-tested integrations; and (4) developer surface area including REST API, CLI, JavaScript SDK, MCP server, embedded UI components, and a self-hosted deployment option on AWS/GCP/Azure for data sovereignty. Notable customers include Bridgestone, Dialpad, PandaDoc, Storyblok, Robin AI, Constant Contact, and Hireology, spanning enterprise, mid-market, and startup segments. The company is SOC 2 Type II certified and GDPR compliant.
Membrane monetizes via subscription-based SaaS pricing with usage tiers and features, supported by a freemium go-to-market combining self-serve developer onboarding (free PoC with working prototype) and direct enterprise sales. The company rebranded from Integration.app to Membrane in November 2025 to reflect its pivot toward AI-agent-first positioning, and operates with only a $3.5M seed round (Nov 2023) led by Crew Capital and Cortical Ventures, with participation from Seedcamp, Accel Starters, DataRobot, and UiPath founders/executives.

Product offeringCore offering
Membrane operates an AI-powered agentic integration infrastructure platform that enables SaaS companies, AI agent developers, and enterprise internal-tool teams to connect any product to any software application through a single unified interface. Developers describe integration needs in natural language, and the Membrane Agent autonomously builds, tests, and maintains integrations across a catalog of 100,000+ pre-built, production-tested connectors using Universal Data Models that decouple integration logic from underlying third-party schemas. The platform is delivered via API, CLI, JavaScript SDK, MCP server, embedded UI components, and a web console, with optional self-hosted or private-cloud deployment on AWS, GCP, and Azure.

integration.app competitors and assessment
Company assessmentBroad incumbents
- MuleSoft (Salesforce): Salesforce-owned enterprise iPaaS and API management platform acquired for $6.5B. Directly competes with Membrane in the integration platform category but bundles tightly with Salesforce ecosystem and serves much larger enterprises.
- Boomi: Established cloud-based integration platform (acquired by Dell, now independent) serving enterprise IT with API management, data integration, and workflow automation. Comparable integration capabilities but broader portfolio positioning.
- Zapier: Consumer and SMB-focused automation platform with the largest connector catalog among non-enterprise tools (~6,000+ apps). Comparable in the no-code/low-code integration category but serves different customer base than Membrane's enterprise focus.
Direct peers
- Workato: Enterprise iPaaS platform focused on business and IT users building workflow automations and integrations. Closely comparable in SaaS-to-SaaS integration use case, with similar API-first architecture and enterprise sales motion.
- Merge: Unified API provider offering a single API for HR, CRM, ATS, accounting, and other categories. Direct competitor in the embedded/SaaS integration category, though Merge focuses on category-specific unified schemas vs. Membrane's universal model approach.
- Tray.io: Enterprise integration and automation platform with a visual builder and extensive connector catalog. Comparable in target customer (mid-market and enterprise) and use case (SaaS-to-SaaS integration), with well-funded operations.
- Prismatic: Embedded iPaaS platform specifically focused on SaaS companies embedding customer-facing integrations. The most direct competitor to Membrane's primary customer segment (SaaS product companies needing embedded integrations).
- Pipedream: Developer-focused integration platform with code-based workflows and extensive API catalog. Comparable in developer-first positioning and API-first architecture, serving similar use cases around workflow automation.
- Make (formerly Integromat): Visual automation platform with strong European presence and competitive pricing for SMB and mid-market. Comparable in workflow/integration use case and SaaS-to-SaaS connectors, though less focused on AI agent integration.
Emerging players
- n8n: Open-source workflow automation platform with self-hosting and AI integration capabilities. Overlaps with Membrane's self-hosting differentiation and developer-first positioning, particularly for technical teams building custom integrations.
